Troubleshooting Mac Power:

Refer to the following....

A. Reset the SMC and your NVRAM:

(Applies yo Intel-Based Macs Only) Sometimes when changes are made to the system(i.e. Updates), system configurations (i.e. for Power) become manipulated, technically. So, reset the SMC and NVRAM. Try performing each thrice. It may take sometime, being certain you have the time to perform these resets.

B. Try a New Charger:

• Power & Cables - Mac Accessories - Apple - Select "Mac Compatibility" on the left
• Find the Right Power Adapter and Cable for your Mac Notebook - Apple Support

C. A Few Links to Refer to for Power:

• About Mac Notebook Batteries - Apple Support

• If your Mac Battery won't Charge - Apple Support

Hi MacHelp_12,

Some additional details would be helpful.

• What year was your MacBook made in? Is it a MacBook, a MacBook Air, or a MacBook Pro?

• Did you drop or water damage the Mac?

• Does anything happen when you press the power button? Does the backlight turn on at all? Do the fans turn on?
